afkickoutelement having a rotatable die Torrent? KICK- Appli-c 'ation-file d November 18, 192

Heret'ofore'in the manufacture of, pottery, and the like in molding machines proyided f with a rotatable core and a stationary mold and nonerotatable kickout, it has been impossible to 'emboss or engrave characters on the bottom of the, pottery due-to the fact that the rotatable core during a molding operation very oftencauses the article being molded to have a slight rotatable movementrelatlve to the mold and the kickout, so that'any charaoters'which might be formed on thearticle would be destroyed or mutilated, due' to; the fact that the kickout is non-rotatable.

,Toovercome the above difliculties this in Vention relates to pottery, molding machines formaking-flower potsand the like, and more particularly to a kickout element h'aving'a rotatable head adapted to Lrotatefwiththe plastic material being molded, said-kickouthead havinggthe upper face thereofengraved onl embos'sedwith characters to form anembikifiting orgimprinting die permitting names, characters or the like to be formed on the bottom of a flowerpot or the like being molded in thefmachine without any danger of-the characters being-destroyed.

1 It is an object of-this invention toprovide: a. pottery molding machine on the rotary eoreand stationary mold type havmg-a rotatable: kiekout die" whereby,v characters or. the like: may be either embossed onor engraved chine; a It is also an obgectv of this invention to provide a pottery molding machine Wllill forming a part thereof, [and 'permitting flower pots to be molded with embossed letters or characters on the bottomthe'reof to designate the name of the manufacturers,- si'ze of'the flowerpot and the'l'ike.

Iti's'an important object of this invention toprovide an improyedkickout element for use in a pottery molding machine'of the ro tary core type, with said element-having a part.thereotandfmovable with the article being molded to facilitateieither"embossing characters and supporting iribson the bottom a punchvpinjor projection12.

The spinner shaft 5 i's-provided with a racksleeve 8 which is:

adapted t'o'be raised or lowered throughqan adjustable bracket 9 by means of a 'control leverfonhandle 10 and a gear (not shown) which is; located within the bracket 9. in 00- acting-relation with the. rack-sleeve '8.

Formed axially on-the Thereciprocating spinner 11 is be movedinto or outfof engagement With'a chine framework. The mold'13-has'theinterior thereof shaped: oomplemental to the ex;

. terior: ofthe spinner 11' to permit, a flower V pot of a'pre'determined shape to be molded inthe-machineV The lower end of the mold 13 7 is provided with an opening- 15 for there a stand- 6 stationary flask or mold 13 supported on atable orshelf 14:, forming a partiofthe mae means of a reciprocating arm 19 which proj'ects outwardly through a slot in the base of H internally threadedpassage21 in the lower. end thereof, while the uppe-re'nd is provided ception of the kickout element The kickout element comprises a kickout shaft or rod 16 which is slidably engaged in a bracket arm 17 mounted on the machine framework. Stop rings 18 are adjustably secured on the-kickout shaft 16 to limit the movement thereof by the machineframework, and is adapted to be operated by any suitable means.

The improved kickout element is adapted to be removably secured on the upperthreaded end of the kickout shaft 16, and as illustrated in Figures 2 and 3 comprises a cylindrical shank or sleeve 20 providedwith an with an enlarged internal passage 22 and with an outlet opening 23 in one side thereof, to permit discharge of plugs punched out of the bottom of flower pots which are molded in the machine. I V The kickout shank 20 is provided with a slightly tapered head 2am upper end of which is formed with a recess 25 in which a ball bearing race 26 is mounted carrying a plurality of bearing balls 27 The kickout head'2 1 is also provided withan upper projecting circular ridge or flange 28 positioned to the outside of the ball bearing mechanism; Rotatably 1 projecting into the upper end of the kickout passage 22 is a hollow stem or tube 29, on the upper projecting end of whicha tapered'kickout die head 30 is rigidly secured.

The under face of the die head 30 is concentrically grooved to interfit with the upper end of the lower kickout head 24, permitting the die head 30 to be rotatably supported on the bearing balls 27 so that the die head 30 and its with-a plurality ofspaced radially directed charactersso'that the same-will form the. name of a company, in addition to numerals grooves-or rec'esses 32. The circular groove 31 forms a peripheral ridge or bead 33 on the die head with said bead 33 being interrupted at spaced intervals by the radial recessesfor grooves 32. The spacebetween the circular groove 31 and the inner periphery of the die head- 30is adapted to be engraved or entwith a'series of letters, numbers or or the like, for designating the size, 'of flower 7 pots which are being formed." If desired the groove space 31may be provided with embossed or engraved characters so that characters may heformedin the bottom rim of the article being molded. g

Bythe use of the improved rotatable die head it will,fof course be readily understood that embossed letters or characters may be readily formed on the bottom of a-flower pot or the like during a mol'dingoperation, and that'ra'dial supportingribs or feet may also be formed on the base of acontainer being 7 -molded without any distortion of the charac; 'ters, since any rotatablemovementimparted to the article being formed by the rotatable core'will-be likewise imparted to the rotatable kickout die'head, thereby obviating any damage being-donefto the characters formed on the bottom of thearticle beingmolded. This arrangement is entirely new in the art and af- 7 fords 'a'convenient means whereby the names and addresses ofthe manufacturers or distributors may be embossed on or engraved in pottery as well asthe particular sizeof the pots or containers whicharemolded in the kickout head 30 to form the'desired letters or characters ,on the :bottom of the potor container which is being molded, Any rotation of "the pot while being formed which might'be caused'by the rotation of the rotat ing core 11 is transmitted to the rotatable kickout head 30, which-consequently is also permitted torotate so that there will be no relativemovement between the kickout head 30 and the rotating core. The letters or char.- acters which are embossed upon the bottom of the potbeing formed will therefore not be iio distorted or injured during the molding process. I At'the' time that the rotating core 11 is lowered to cause the shaping of a flower pot within the mold 13 the punch pin 12 will punch out a plug from the middle of the base of the flower pot, leaving a hole in the middle central portion of the flower pot when the core is withdrawn and the finished pot'is removed from the mold. The punched out plug is permitted to-drop through the. passageprovided in the tube 29 of'the 'kickout head intothe bottom ofthe passage 22 from which the plugmay be discharged through the opening 23. f 7

After. a flowerpot has been completely molded as-hereinbefore described, the rotat ingcorell is retracted-from its engagement within the formed pot, after whichthe reciprocating bracket 19 is'joperated to cause the kickout element to be projected upwardly in the mold '13 'to' cause the" formedflower its 7 moved fromthemoldingimaehinei-s V j, With'the improved iki koutselement of liead, flower pots and similar 'potterylt'ormed inmolding machinaiimay have the-mamas of manufacturers embossed'onthe bottom thereof; as wellas numerals or characters indicating the particular size'ofithepot. rigAttention is also .called to the' factijthati the improved rotatable kickouthead furthermore permits mam rihsfor t-he lilie tobe integrally embossed or formed on thev bottom of a flower pot or the like to permit the bottom of the flower pot to. be slightly spaced fromthe table or floor on which it is standing to provide an air or drain space beneath the flower pot. j p v The rotatable kickout die head 30 may be provided with radial I'lbSQlIl place of-the radial grooves 32, in which" case radial outlet or drain grooves will be formed in the bottom rims of molded pottery instead of the radial ribs or feet. 'The bottoms of the articles being molded may therefore have 'char-' acters embossed thereon or engraved or stamped therein as desired, depending upon whether the rotatable kickout die head is engraved or embossed.

The improved rotatable'kickout device not onlypermits pottery to be molded and simultaneously embossed or engraved with charactors, but furthermore affords an arrange-V ment of parts whereby the pottery may be perfectly molded without any scraped or' strained sections which usually results in the old type 'of machines from relative twisting movement between the material being molded and the stationary kickout element and mold;

I am aware that numerous" details in the above specification maybe variedthrough a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise thanv necessitated by the priorart. V
